Smart home maintenance

Firmware and app updates fix security vulnerabilities as well as bugs, so keeping current genuinely matters on internet-connected hardware. The sensible compromise is to enable automatic updates on non-critical devices and to apply major updates to critical devices a few days after release, once other people have found any problems.

Batteries. Smart locks, door sensors and cameras all run down. Set a calendar reminder rather than waiting for the low-battery notification you will miss, and always keep a physical key for a smart lock.

Account security. These accounts control cameras, locks and heating in your house. Use unique passwords and turn on two-factor authentication everywhere it is offered. Remove access for anyone — including a former installer — who should no longer have it.

The annual review. Walk the list of devices. Delete automations nobody uses, remove devices that no longer function, confirm your critical automations still fire, and check whether any manufacturer has announced an end-of-support date for something in your house.

How to choose

Put battery changes on a calendar

Annual replacement for locks and door sensors beats waiting for a notification you will ignore.

Enable two-factor authentication everywhere

These accounts control physical access to your home. Treat them like a bank login.

Audit who has access once a year

Remove old housemates, former installers, and any guest accounts that are no longer needed.

Test critical automations deliberately

Trigger the leak alert and the lock automation on purpose once a year. Do not assume they still work.

Keep an inventory

A simple list of device models, locations and accounts makes troubleshooting and warranty claims far easier.

Watch for end-of-support announcements

Manufacturers do retire cloud services. Knowing early gives you time to replace a device on your terms.
